MCQ - 96-2282

Question:

What is the enthalpy change for the following reaction? 3C(s) + Fe2O3(s) → 2Fe(s) + 3CO(g)

  1. +712kJ mol-1
  2. +492 kJ mol-1
  3. -492 kJ mol-1
  4. +492 kJ mol-1

Correct Answer: B

Explanation:

3C(s) + Fe2O3(s) 2Fe(s) + 3CO(g)

17 -13823461
3 × (-110)kJ
3CO(g) + Fe2O3(s)
ΔH = 3 × (-110)-(-822)
= + 492 kJ mol-1
